Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Pennsylvania for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Pennsylvania only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Pennsylvania (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider is heavily concentrated in intravitreal anti-VEGF therapy: J0178 (3.3K claims, $691 avg paid/claim, $2.3M revenue, 38.6% of total) and J2778 (6.6K claims, $189 avg paid/claim, $1.2M revenue, 20.9% of total) are the top two revenue drivers, with Q5128 (4K claims, $216 avg paid/claim, $863.6K revenue, 14.4% of total) completing a three-code core that reflects a practice focused on high-volume retinal injection services. The precomputed top-3 share confirms this concentration: the top 3 Medicare codes by revenue account for 73.9% of this provider's total Medicare revenue, signaling a service-line strategy centered on frequent medication injections for retinal disease.

The provider’s Medicare scale is substantial: lifetime Medicare revenue is $6M while Medicaid revenue is none, indicating an effectively single-payer footprint concentrated in Medicare; there is no Medicaid billing on file to balance or diversify payer exposure. This payer mix implies the practice primarily serves the Medicare population for its high-volume retinal injection and ophthalmology services rather than Medicaid cohorts.

National competitive standing for key injection codes is strong. J0178 ranks #126 of 3204 providers nationally (96th percentile; notably above typical national volume for this code), J2778 ranks #24 of 1208 providers nationally (98th percentile; notably above typical national volume for this code), and Q5128 ranks #21 of 373 providers nationally (95th percentile; notably above typical national volume for this code), which together position the provider as a major national-volume participant in anti-VEGF and biosimilar intravitreal therapy.

Beyond injections, diagnostic and follow-up ophthalmology codes also show unusually high volumes: 92012 (3.3K claims, $68 avg paid/claim, $222.9K revenue, 3.7% of total) and 92134 (5.4K claims, $31 avg paid/claim, $167.5K revenue, 2.8% of total) both rank in the 100th percentile and are flagged as extreme outliers, indicating a high throughput of intermediate established exams and retinal imaging that supports a procedure-heavy retinal practice. This code mix suggests integrated visit-and-treat workflows where frequent imaging and follow-up visits accompany the injection regimen.

There are several statistical outliers in the provider’s Medicare profile that mark this practice as far above typical national volumes for certain services: 67028 (3.7K claims, $98 avg paid/claim, $360.3K revenue, 6.0% of total) is described as an extreme outlier, and 99204 (252 claims, $124 avg paid/claim, $31.2K revenue, 0.5% of total) also appears as an extreme outlier. These flags indicate unusually high utilization for specific procedure and new-patient visit codes relative to national peers and warrant attention when benchmarking utilization patterns.

Surgical retina and broader ophthalmic procedural activity is present but limited relative to injection and imaging volumes. For example, 67042 shows only 13 claims ($927 avg paid/claim, $12.1K revenue) and 67028 dominates vitreous injection coding with high volume; this suggests the practice emphasizes office-based intravitreal therapy and diagnostics rather than frequent complex vitreoretinal surgery.

Tenure and experience are notable: the NPI was enumerated on 2006-02-14 (~20 years ago), indicating long-term presence in the market which, combined with the high-volume ranks on multiple codes, supports an established practice with sustained Medicare billing patterns over time.

The overall revenue-concentration and payer mix profile imply business and network considerations: with $6M in Medicare revenue and no Medicaid billing, the provider is highly dependent on Medicare reimbursement and on maintaining referral and retention pathways within the Medicare-aged population. Payors and competitors assessing network strategies should view this entity as a specialized, Medicare-focused retinal/injection center with significant capacity and national-level injection volumes.
